Hi @muneera _al-kubaisi
I understand the problem you are facing !
It means your account password is change or due to security reason your account is disabled ( Locked) - So you will required to contact the admin of the store to unlock ( enabled ) your account !
If you have server/SSH access then you can also unlock your account by running below command :
php bin/magento admin:user:unlock ADMINUSERNAME
you will required to run this command from the root of the Magento 2 directory !
You can also reset username and password of your account by running below command :
sudo php bin/magento admin:user:create --admin-user="pearlbells" --admin-password="pear122l**all" --admin-email="pearl@gmail.com" --admin-firstname="Admin" --admin-lastname="Admin"
Hope it helps !
